    Abstract

    Lack of a suitable selection device to suppress sneak current has impeded the development of 4F 2 crossbar memory array utilizing stable and scalable bipolar resistive-switching. We report a high-performance nonlinear bipolar selector realized by a simple Ni/TiO 2 /Ni MIM structure with a high current density of 10 5 A/cm 2 , and a Ni/TiO 2 /Ni/HfO 2 /Pt vertically stacked 1S1R cell capable of gigabit memory implementation. Furthermore, the demonstration of 1S1R array fabricated completely at room temperature on a plastic substrate highlights the promise of future extremely low-cost flexible nonvolatile memory.
